40% Of Subscriptions Happen Inside Substack. Here's How To Be Found.
Substack rebuilt how readers find writers. If you're still relying on outside traffic, you're missing the biggest growth shift on the platform.
Want to grow your Substack and actually build a brand here?
I got you. I’ve spent the last 2 years doing exactly that. Pivoting, figuring things out the hard way, staying on top of every algorithm change and platform shift so you don’t have to. If you don’t want to do this alone, join me.
Last Tuesday I was staring at my subscriber analytics and something didn’t add up.
I’d barely posted on Medium. My LinkedIn had been quiet for weeks. I hadn’t done a single collab or guest post. But my subscriber count had jumped by over 400 in 10 days.
So I dug into the data. Where were these people coming from?
87% of them: internal Substack discovery.
Not Google. Not social media. Not a recommendation from another writer. Substack’s own app showed them my content, and they subscribed.
I thought it was a fluke. It wasn’t.
Let’s dive in.
Substack Quietly Rebuilt How Readers Find You
Here’s what happened and why most writers missed it.
In late 2025, Substack overhauled its entire recommendation engine. The feed, the thing readers scroll when they open the app, stopped being a simple chronological list of people they already follow. It became a discovery engine.
The numbers back this up. According to Substack’s own reporting, 40% of all subscriptions now come from inside the Substack network. Not from external links, not from Google searches. From readers browsing the app and finding writers they’d never heard of. And 15% of paid subscriptions originate the same way.
With 50 million+ active subscriptions on the platform, that’s tens of millions of people who found their favorite writers without ever leaving Substack. That’s a massive shift. And it changes how you should think about growth.
For years, the advice was: build an audience somewhere else (Twitter, Instagram, LinkedIn), then funnel them to your newsletter. That still works. But it’s no longer the primary growth channel for most successful Substack writers.
The primary channel is now Substack itself.
→ As I couldn’t keep up with writing DMs, I built myself a tool for it. Of course ;).
What the Algorithm Actually Looks For
I know “algorithm” is a loaded word. But understanding this matters.
Substack’s recommendation system isn’t optimizing for engagement metrics the way Instagram does. It’s not trying to keep you doom-scrolling. The goal is subscriptions. Connecting readers with writers they’ll actually want to follow long-term.
Here’s how it decides who to show your content to:
Audience overlap. If someone subscribes to three newsletters about creator business and you write about creator business, your content gets surfaced to that person, even if they’ve never heard of you.
Reader behavior signals. Location, language, which writers they follow, what topics they’ve told Substack they care about. The algorithm matches your content to readers based on these characteristics.
Your engagement pattern. This is the part most writers overlook. The algorithm doesn’t just look at what you publish. It looks at whether you’re actively participating on the platform. Writing Notes, engaging in comments, restacking other writers’ work. Sporadic posters are getting buried. Writers who show up consistently are getting surfaced.
Content freshness. Recent posts and Notes carry more weight than content from two months ago. The algorithm favors active, producing creators.
The 80-90% Drop Nobody Talks About
Here’s the uncomfortable truth. A lot of writers saw their subscriber growth drop 80-90% in 2025. They kept publishing. They kept writing good content. But the growth stalled.
What happened wasn’t a quality problem. It was an adaptation problem.
These writers were still operating on the old model: publish a post, share it on social media, hope people click through. Meanwhile, Substack was redirecting discovery to happen inside its own ecosystem and the writers who weren’t showing up there became invisible.
I watched it happen to writers I respect. Smart, talented people who just didn’t adjust.
The ones who did adjust: Their growth accelerated. Because when you work with the internal discovery engine instead of fighting it, you’re accessing an audience of 35+ million active users who are already inside Substack looking for content.
5 Things I Changed (And You Can Too)
I’m not going to pretend I figured this out immediately. I stumbled into most of it.
1. I Stopped Treating Notes as Optional
In my last post I broke down the data on Notes — 54% of my new subscribers come from them, and I’ve seen a single Note bring in 1,545 subscribers. That hasn’t changed. But here’s the piece I didn’t emphasize enough:
Notes aren’t just a growth tactic. They’re your visibility signal to the algorithm.
When you post Notes consistently, you’re telling the discovery engine: “I’m here, I’m active, show my work to people.” When you don’t, you’re invisible to the 32 million potential subscribers browsing inside the app.
2. I Started Engaging Before I Published
Old habit: write article, hit publish, share on social, wait. New habit: spend 15-20 minutes engaging with other writers’ Notes and posts before I publish anything.
Why? Because the algorithm tracks reciprocal engagement. When you engage meaningfully with other creators in your niche, their readers see your activity. And those readers often overlap with your ideal subscriber.
It feels backwards. It works.
3. I Optimized My Substack Homepage
Most writers set up their homepage once and forget it. I went back and treated it like a landing page.
Pinned my best-performing post. Rewrote my “About” section to speak directly to the person discovering me for the first time through the app (not someone who already follows me on Instagram). Made sure my first three visible posts represented the range of what I cover.
When the algorithm surfaces your Note or article, the reader clicks through to your profile. Your homepage is your first impression for 32 million potential subscribers. Make it count.
4. I Leaned Into the Community Features
Chat. Comments. Restacking. These aren’t nice-to-haves anymore. They’re engagement signals.
Substack is watching whether your subscribers interact with you, not just whether they open your emails. Writers with active communities get boosted. Writers with silent subscriber lists don’t.
I started asking questions in Chat. I respond to every comment on my posts. I restack work from writers I genuinely admire (not as a strategy, but because I actually want to share it, and the algorithm rewards authenticity).
5. I Used the New Features Before Everyone Else
Substack rolled out email automations to select creators in 2025, and it’s expanding to everyone in 2026. Video content is becoming part of the mix. These new features aren’t just tools, they’re signals that you’re a power user, and the platform tends to reward early adopters with visibility.
When a new feature drops, I test it within the first week.
The Bigger Picture: Substack Is No Longer Just a Newsletter Platform
This is the shift I want you to really sit with.
Substack started as a place to send email newsletters. That’s it. You wrote, people subscribed, emails went out.
Now it’s a community platform with Notes, Chat, live video, podcast hosting, email automations, and an internal discovery engine that’s driving 32 million new subscriptions per quarter. Instagram and YouTube creators are migrating here as a primary platform, not a side channel.
The writers who are growing fastest in 2026 aren’t thinking “how do I get more email subscribers.” They’re thinking “how do I build a brand on Substack.”
That means showing up across all the features. Publishing articles, yes. But also posting Notes daily, engaging in Chat, going live, using automations for onboarding sequences, and treating your Substack as a home base.
A Quick Update for my Premium Subscribers
Speaking of showing up consistently, I just updated the paid subscriber experience.
Your Wander Wealth paid membership now includes the Notes Scheduler at no extra cost. This is the tool I use to batch-write and schedule my Notes for the week, and it’s the same one I talked about in my last post.
If you’ve looked at other scheduling solutions out there, you know they charge 3x what a Wander Wealth membership costs, just for the scheduler alone. You’re getting it bundled with everything else: the full archive, community Chat access, templates, and all future tools I build.
If you’re not a paid subscriber yet and the Notes scheduling piece has been your sticking point, this might be the nudge.
Your 10-Minute Action Plan
Don’t just read this and nod. Do something with it today.
1. Open your Substack analytics. Look at where your subscribers are actually coming from. Specifically check “Substack internal” vs. external sources. The ratio might surprise you.
2. Audit your homepage. Pretend you’re a stranger who just discovered you through a Note. Does your About section speak to them? Are your pinned posts your best work?
3. Post a Note right now. Not tomorrow, not after you’ve “planned your content calendar.” Right now. One thought about what you’ve been working on, learning, or struggling with. The discovery engine needs activity to work with.
The writers who grow in 2026 won’t be the ones with the best content. They’ll be the ones who understood that the game changed and changed with it.
